Bleeper

Create sound effects by drawing volume and pitch sequences, using the 8 waveforms to choose from. Right-click to remove steps in the sequence. Hold shift to only change the waveform. Adjust sound duration (speed), pitch range, or snap pitch to the chromatic scale.

When you are done editing, exports all your sounds to mp3 or wav audio files. Or save your program as text data for future edits.
